Model 1420

The Groth 1420 pilot-operated relief valve with pipe-away feature is used to replace weight loaded or spring loaded valves in many applications to increase efficiency and reduce evaporation losses. Several advantages are obtained over the traditional type. For example, the process pressures may be closer to the set pressure than would be considered prudent and safe with the traditional valve. Additionally, greater conservation is obtained due to minimum product loss which in turn provides increased profits.

Features

PILOT OPERATED• Ease of precision settings• Only the pilot needs to be set• Lower profile and weight than spring operated models for high settings• Remote pilot sensing option allows the pilot to sense the true system pressure• Remote or manual blowdown available

EXTRA TIGHT SEAL• Main valve remains tight to set pressure

FULL FLOW• Full open at 10% overpressure

SNAP-ACTION OR MODULATING ACTION• Modulating action conserves product since valve opening is proportional to overpressure.• Noise is reduced since the valve only opens fully when required.
